The catastrophic earthquake that struck on March 11 off the northeast coast of Japan has caused many weak (less than 3 magnitude) earthquakes around the world, reports Livescientist.

They were mostly recorded in seismic regions — in the Taiwan area, the Aleutian Islands, in Canada, in the U.S. states of Alaska, Washington, Oregon and California. Much more interesting for experts was the fact that the Japanese cataclysm caused aftershocks where nothing like previously observed, such as Cuba. Aftershocks were also reported in areas where earthquakes happen, but with very small magnitudes — in the outskirts of Beijing and the

Earthquake in Japan would not have caused such catastrophic damage if they were not accompanied by an unusually strong liquefaction of soils in an area of hundreds of square kilometers. This is the conclusion of a team of researchers at Oregon State University, who worked on the site of earthquakes.

Due to the fact that the earth has suddenly become unstable, many buildings moved from their seats, tilt and partially left in the soil, although they are not directly earthquake damaged. Shifts diluted soil destroyed not only buildings, but also water, sewer and gas pipelines in the number of

Specialists of the Institute of Seismology of the National Academy of Sciences of Kyrgyzstan predicted 9-magnitude earthquake (on a 12-point scale MSK), which may occur in the republic this year.

According to the Minister of Emergency Situations of Kyrgyzstan Borbieva Marsh, currently in the phase of the republic came the highest seismic activity, which will continue until the end of 2012, reports portal TSN.

It is noted that since 2011 the country has more than 30 earthquakes, the power of some of them up to 6 points. Borbiev adds that over 75% of citizens live in areas of high seismic

It turns out, the tsunami that hit the Japanese islands and caused the accident at the plant, it was possible to trace in advance and, therefore, time to warn the population. It turned out that before the crash floor of the Pacific Ocean publish incredible noise. His recorded underwater microphone or hydrophone, which was lowered into the Pacific Ocean in an area of 1400 km from the epicenter of the earthquake

Nevada Seismologists are closely monitoring for the area south-west of Hawthorne, Nevada, where on Sunday were recorded hundreds of earthquakes.

"There is some sense of concern … large earthquake with such consistency is quite common," said the director of the Nevada Seismological Laboratory at the University of Nevada Graham Kent. He said that over the past few days to the south-west of Hawthorne, there were several hundred earthquakes. The largest was a magnitude of 4.4 points.

"This is the largest order that we have seen over the last couple of years." Kent said that in contrast to the earthquake

These findings are confirmed by a resident of the northern capital Oleg: "In the north of St. Petersburg home again shake from explosions, apparently made by one of the polygons in Sertolovo," — he says.

Letters from readers on this topic keep coming. Add that "Fontanka" wrote about tremors of unknown origin in February. However, reliably determine the cause of what is happening and failed.

In the northern part of the Chilean State earthquake with magnitude 4.9.

According to the U.S. Geological Survey, an earthquake was recorded at 4.25 Moscow time. Its epicenter was located in 1350 kilometers from the capital Santiago and 127 kilometers north of Calama.

The earthquake lies at a depth of 102 kilometers, information about victims or damage were reported.

Chile is in the area of so-called Pacific "Ring of Fire", where 90% of all earthquakes in the world. Band of volcanoes and tectonic faults longer than 40 thousand kilometers encircles the Pacific Ocean.

Off the coast of Puerto Rico, an earthquake of magnitude 4.4, announced today the U.S. Geological Survey. Earthquakes have been recorded at 12:28 MSK. The hearth was at a depth of 18 km under donm Atlantic Ocean 123 km north of the capital of Puerto Rico, San Juan. No injuries or damage were reported.

Located in the Caribbean Sea Puerto Rico is administered by the U.S. and has the status of "an organized unincorporated territory", that is not an integral part of the United States. This means that residents of Puerto Rico have in common with U.S. citizenship, currency
